      abstract     = {n this work, we studied the bulk band structure of a
                      topological insulator (TI) Bi2Se3 and determined the
                      contributions of the Bi and Se orbital states to the valence
                      bands using standing-wave excited hard x-ray photoemission
                      spectroscopy (SW-HAXPES). This SW technique can provide the
                      element-resolved information and extract individual Bi and
                      Se contributions to the Bi2Se3 valence band. Comparisons
                      with density-functional theory calculations (local density
                      approximation and GW) reveal that the Bi 6s, Bi 6p, and Se
                      4p states are dominant in the Bi2Se3 HAXPES valence band.
                      These findings pave a way for studying the element-resolved
                      band structure and orbital contributions of this class of
                      TIs.},
